SPECIFCATION forming pari: of Letters Patent No. 363,577I dated May 24,1887. Application filed February 10l 1857. Serial No. 227,134. (Nomodel.) Patented in Belgium November 2, 1886, N5, 75,0?1.

To all whom, it magy concern.'

Be it known that we, HART C. BERG, of Brick Church, Essex county, NewJersey, and ADOLPHE Dnconris, of Charette, Province of Liege, Belgium,have invented n new und useful Improvement in Hnmmcrlcss Gnus, whichimprovement is fully set forth in the following specification.

This invention hns reference to the construction of breeclrlondingsmnllnrnis, and more particularly to the soenlled hammerless guns.7

The object of the invention is io improve in several respects the actionof the gun with n view to securing greater simplicity, cheapness Ofmanufacture, and less liability to get ont or" order. t

In guns of this class many different devices have been contrived wherebythe cooking of the gun is effected by the dropping down oi the barrelsto remove the exploded cartridge. Guns or" this elnss have also beencontrived in sneh wey that 'the dropping down of the harrel raises 'the.hammer to linll'-cock, and the cooking is completed by the returnmovement of the barrels to their normal position.

According to the present invention the linminers nre half-cocked by thekey when the lotter is turned to withdrew the bolt end permit thedropping down of the borrels, the hinniner being in contact with the endoi the boit.l and. the iitnimers are carried to full-nook by thedropping down of the barrels, en incline or cam snrince on the i'orw Illump acting against the end ei' the bolt, onsliin n iin of itsmotion.

Lne liner nier is eur-ri on rod eneircled lov n spiraal spring, eostitntes the me* ring of e rod is pushed bock by the eoiion o; np endbolt, the spring ic ooinpressed, s thereby put in operative positionThis use of n sp l s ring the f tutes In the present invention the senris n leefspring screwed at one end tothe trigger-platte and having odetcnt for engagement with the notches of the tumbler near its free cud.In firing, the trigger dcpresses thesezugrelensing the hammer. Incooking the gun n rod in Contact with the bolt is pushed back. This rod,acting through an intermediate lever, forces n sliding block under thesenr, which prevents the letter being depressed to release the hem mer.The dropping down ofthe bnrrels therefore cocks the gun andautomatically locks the senr in n position of safety. Connections arealsol provided for locking nud releasing the senr by hand. Thisconstruction of the senr and safety mechanism is simple and effective.In ordinary gun-notions the Sear is o,- pivoted piece under theinfluence of aspiring. In the present invention the pivoted piece isdispensed with. Thefrepented lifting oi' the senr-spring by the slidingbnr tends to prevent loss of resiliency of the spring, and thereforeincreases its durability.

The forward lump, which nets upon the bolt to cool; the hummer, hns twocem-farces inclined; in opposite directions. The object of the second orlower cem-fece is to oct upon the bolt end push it beck in order toreplace the borrels when the lntterlinvc been removed entirely from thestock, as i'or purposes of transportation.

the breakbff, and its rear end (shown in Fig. III) is in` contact withthe hammers 8, (only one of which isshown in the drawings.) The hammer 8is carried by a rod, 9, which slides in a hole in the break-off. Aroundthis rod is coiled a spiral spring, 10, which constitutes themainspring. The bolt 7 has on its under side projections 11 12. (SeeFig. IV.) In contact with projection 11 is a key, 13, on the lower endof a shank, 14,to the top of which is screwed a hand-lever, 15.

As shown in Fig. I, thelockingedges of the bolt are in the recesses and6 ofthe lumps 3 and 4, and the barrels are therefore locked in place.When the key 13 is turned by the bandi lever 15, as in Fig. II, itvpresses against the projection 11 of the bolt 7 and withdraws thelatter from the recesses 5 and 6. By the same motion the rear end of thebolt, acting against the hammer 8,withdraws the latter sufiiciently forthe first notch of the tumbler 16 to be engaged by the sear 17. The gunis then at halfcock, the mainspring being but slightly compressed. Thefront edge of the bolt 7 is now in a position to,y be acted upon by theincline or cam-surface 18 of the forward lump, 2, and as the barrels aredropped down this cam-surface gradually pushes back the bolt, andconsequently the hammer also, until the parts assume the position shownin Fig. II, the hammer 8 being then at full-cock.

lThe mainspring 10 bears at its forward end against the collar 40, xedon the end of the rod 9,and at its rear end against the loose collar 41.The latter is held in the recess by the head of screw 42. Thus, when'the rod 9 is pushed back, the collar 41 remains stationary, being heldby the head of screw-42, whereby the mainspring is compressed. Thehammer and mainspring can be readily removed, if desired, by taking outthe holding-screw 42.

Above the rod 9 is a small guide-rod, 43,at tached to the hammer 8. Thisrod 43 works in a hole, 44, in the break-off. (Shown in Fig. III.)

The sear 17 is a leaf-spring screwed at 20 to the trigger-plate 39, andhaving near its free end a catch or detent, 2l, which engages thenotches in the tumbler 16. The scar projects baekwardly, and the forwardend of the trigger 19 bears directly upon it, so as to depress the searto release the hammer and discharge the gun.

The upright pin 45, fixed to the triggerplate, bears at its upper endagainst the underside of the tumbler 16. When the sear is depressed bythe trigger, there is a tendency to draw the tumbler down with it, andthus' end can slide under the sear, locking the latter in place. Thisbar is slotted (see Fig. V) so as to embrace the stationary block or lng38, in which the triggers 19 are pivoted. To the rear end of sliding bar22 is pivoted a lever, 23, fulcrumed at 24 in the block 38. To thislever, on the other side of the fulcrui'n, is pivoted a rod, 25, whichis slotted near its end for the passage of the fastening-screw 37. Thisrod 25 projects forward'between the hammerssuiiieientl y far to bestruck by the bolt 7 before it reaches the backward limit of its motionunder the influence of the cam 18.

As shown in Fig. III, the hammers have grooves 36 for the passagebetween them of the rod 25. When the rod 25 is thrown back by themovement of the bolt 7, the lever 23 is thereby operated to push the endof the bar 22yunder the sear, as shown in Fig. II. The upper end oflever 23 is embraced by the forked end of slide, 26, whereby it can beoperated by hand to either lock or unlock the' sear.

A light spring, 27, engages a pin, 28, on the bar 22, bearing withsufficient pressure to prevent the accidental movement of the latter.

When the barrels are raised again into their normal position, the bolt 7is automatically thrown into engagement with the lumps by the action ofa spring, 30, screwed at one end to the tail-piece 31 and at the otherentering a notch in the shank 14 of key 13. When the handle 15 is movedto one side, it turns against the pressure of the spring 30; hence thelatter tends to return it to its normal position as soon' as the bolt isfree from contact of the cam 18.

As clearly shown in Fig. IV, the key 13 always has a bearing on the bolt7, by reason `of the projcctions 11 and 12, so that in ease of failureof the mechanism to act properly the bolt can always be thrown by handby means of the key and its operatinghandle 15.

The striker'pins 32 slide freely in holes in thebreakoif. They are heldin place and their motion limited by a holding piece or bar, 33, letinto a groove in the break-ofiI and fastened by a screw. The ends of thebar 33 extend a short way into the holes provided for the striker-pins,ythe Shanks of the latter being cut away for a short distance from theirrear ends sufficient to permit the requisite longitudinal movement.

The forward lump, 3, of the gun, in addition to the cam-surface 18, hasa second cam-su rface, 35, beneath the formerand inclined in theopposite direction. In-the ordinary action of thegun this cam performsno function. When, however, the barrels have been removed entirely fromthe stock, as for convenience in packing for transportation, and it isdesired to put the parts together again, the bolt7 has to be pushed backto its farthest limit against the pressure of both mainsprings. Thiswould be very difficult but for the secon'd incline or camsurface, 35,on the lump, which performs duplication of that described.

ltwil'l furtherbe understood that4 'parts`of the invention may be usedwithout the whole,

` and that modifications maybe made in details spirit of the saidinvention.
